I wrote, previously, about the "Three Laws of Thermodynamics.
Since these laws may be unclear to a great many people, by response, I
have attempted to /" 'splain/ " the meanings. But they may not "simple"
to the non-scientific audience. (Not a gripe, just a fact.)
My "simplification" (not original) was:
1. You cannot win.
2. You can't break even
3. You can't get out of the game
The scientific statement is somewhat esoteric, requiring a knowledge of
mathematics and thermodynamics:
1. If a system undergoes a thermodynamic cycle, whether it becomes
warmer, cooler, larger, or smaller, then it will have the same
amount of energy each time it returns to a particular state.
Mathematically speaking, energy is a state function and
infinitesimal changes in the energy are exact differentials.
i.e., "No change in energy in a closed system" can be loosely
described as "You can't win!"
2. In a simple manner, the second law states that "energy systems
have a tendency to increase their entropy" rather than
decrease it.
i.e., "No change in energy in a closed system" can be loosely
described as "You can't break even!"
3. The third law states
"As temperature approaches absolute zero the entropy of a system
approaches a constant minimum."
i.e. can be thought of as meaning you can't evade the first two laws.
or "You can't get out of the game"
If you would like to read a FULL description you can try "Wikipedia"

Our understanding of them started in 1824, when first formulated.
